JEWELRY FASTENING.

(Application led Nov. 29, 1899.)

BERNARD CONLAN, OF NEWARK, NEV JERSEY.

SPECIFICATION forming part of Letters Patent No. 645,071, dated March13, 1900. Application filed November 29, 1899. Serial No. 758:625. (Nomodel.)

To alt whom t may concern:

Be it known that I, BERNARD CONLAN, a citizen of the UnitedStates,residing in Newark,in the county of Essex and State of NewJersey, have invented certain new and useful Improvements inJewelry-Fastenings; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make anduse thesame, reference being had to the accompanying drawings, and to lettersof reference marked thereon, which form a part 0f this speciiication.

My invention relates to the mechanical devices used for lockingdog-collars, ladies belts, and all such like articles, and. is animitation in its design of an ordinary padlock.

The object of my invention and the improvement thereby made in these`jewelryfastenings is that instead of having a lock as ordinarily madewith a corresponding key attached by a chain to the padlock or insteadof a spring device which by the manipulation of a tongue protruding intothe keyhole releases the hinged curved locking-arm I have furnished apadlock of which the main body, including the larger part of said curvedlocking-arm, can be stamped out of sheet metal preferably or out of anyother material found suitable for such purpose, the hinged memberforming only a small part of the curved locking-arm, as will be observedin the ensuing description. The said hinged member further locks itselfautomatically to themain body, consequently obviating the use of a keyor other locking means, said hinged member interlocking with the mainbody simply by being pressed in over it and unlocking by being pulledapart from it. This will of course reduce the cost of such articles to agreat extent, besides being an innovation'on and simplification ofpresent locking means in this class of articles.

In describing my improvement I shall call attention to the accompanyingdrawings, wherein like letters of reference indicate corn respondingparts in the different vie-ws.

Figure 1 shows a front view of myimproved imitation padlock; Fig. 2, asimilar view of the padlock to the one shown in Fig. l, having thepivoted element removed. Fig. 3 is a side view of the padlock as shownin Fig. 2. Fig. 4t is an inside view of the hinged element. Fig. 5 is afront View of the hinged element, observing it as it is attached on thepadlock in Fig. l; and Fig. 6 is an outside View of the hinged element.V

A indicates the main body of the padlockthat is, the part usuallyinclosing the locking devices of different constructions B', the rstpart of what may be in an ordinary padlock hinged at C, which, however,here forms a solid integral part of the main body A; B2, the second orupper circumferential part of the curved arm,which similarly can behinged at either D or C, in the latter case B and B2 being solid at D,the parts B', B2, and A, however, in my improvement all forming oneintegral part, and finally B3 is the loose and hinged element, theattachment of which to B2 and A is as follows: A pin H secures part Bapivotally to the part B2, thus forming a joint, and the means forlocking said hinged arm Bs to the main body A is a protuberance I,stamped out on the front side of the main body A, as seen in Figs. 2 and3, and a corresponding indentation K on the rear side. The movablepivoted element B3 is furnished with a similar protuberance andindentation, respectively, I on one of the inner sides of the hinge-leafL corresponding to the protuberi ance I on A and KV corresponding to K.

The clasp or curved arm is made in one solid part with the main body ontwo-thirds of its circumference, the remaining third being pivoted andmade attachable to the main I body A, as above described.A

In the use to which these diminutive padlocks have been put the strainhas been generally found to act in the direction of the arn rows and andas it might be found practical and convenient to utilize them on otherarticles where a strain acting at a right angle to the strain indicatedby said arrows-for instance, in the direction of arrows y and g/-i theelement B3, which now is hinged, could then of course be madea solidpart of the main body A, similar to the part B', and the part B2 bepivoted at point D and secured at point H in the same manner part Bs isfor present purposes secured to the main part A. This latter methodwould of course in no wise IOO be any innovation on what I have shownand the `body member having a protuberanee and described in the relationof the hinged part corresponding indentation cop'erating with B8 to themain body A, for the hinged member substantially as and for What Iclaim, and desire to secure protecthe purposes described. v 15 5 tionfor by Letters Patent, is- In testimony that I claim the foregoing I Thecombination in a jewelry-fastening in have hereunto set my hand this 27th day of the form of a padlock, of a body member in- November, A.
